The idea is to paint all the dishes black or white, so use spray primer to coat any of the dishes that aren't either of those colors.

Spray-Paint

Once the spray primer is completely dry, use black and/or white spray paint to coat all of the primed surfaces.

Attach Eyes

Apply craft glue to the back of a pair of googly eyes (Image 1), then attach one set of googly eyes to each pumpkin (Image 2). Tip: Place the pumpkins in the dishes before you attach the eyes so you can make sure they're positioned correctly.
